Big Bus Tours has been bought by thetrainline’s former parent company, Exponent Private Equity.
The company, which offers sightseeing trips in 16 cities around the world, was originally founded in 1991.
It was owned by the Maybury family and Abu Dhabi-based Al Fahim Group, both of which are selling shares to Exponent.
"We are delighted to be investing, alongside the management and existing shareholders, in Big Bus Tours. The business is the industry leader in an exciting and growing market," Exponent’s Richard Lenane said in a statement.
Exponent sold thetrainline to US group KKR earlier this year for more than £500 million. It also owns Quorn Foods and recently floated shares in HSS Hire.
